Descriptions

The htcpHandleTstRequest function in htcp.c in Squid 2.x before 2.6.STABLE24 and 2.7 before 2.7.STABLE8, and htcp.cc in 3.0 before 3.0.STABLE24, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets to the HTCP port.

La función htcpHandleTstRequest en el archivo htcp.c en Squid versiones 2.x anterior a 2.6.STABLE24 y versión 2.7 anterior a 2.7.STABLE8, y en el archivo htcp.cc en versión 3.0 anterior a 3.0.STABLE24, permite que los atacantes remotos causen una denegación de servicio (desreferencia de puntero NULL y bloqueo del demonio) por medio de paquetes creados hacia el puerto HTCP.
